Darien Roseen, a retired vice president of Weyerhauser Real Estate, says his vehicle was stopped in January 2013, shortly after Colorado voters had passed the sale of recreational marijuana.

A Colorado man has filed a federal lawsuit against the State of Idaho, alleging that he was a target of what he calls "license-plate profiling."

The Denver Post reports that 69-year-old Darien Roseen says he was unlawfully detained and searched for marijuana by Idaho State Police because he had Colorado plates.

Roseen, a retired vice president of Weyerhauser Real Estate, says his vehicle was stopped in January 2013, shortly after Colorado voters had passed the sale of recreational marijuana. Roseen said he had just pulled off I-84, just inside the Idaho/Oregon border, to use the toilet at a rest stop. That's where he said ISP told Roseen hadn't properly signaled before exiting. Roseen said an ISP trooper asked, "When is the last time you used any marijuana?" Roseen said he had never used marijuana.

Ultimately Roseen was driven to the Payette County Sheriff's Office, was issued a citation of careless driving, and after law enforcement searched Roseen's vehicle, no drugs were found.

Roseen's lawsuit is seeking general and punitive damages. A representative for ISP said the department would issue a statement on the litigation later this week.
